Android: Although there are a lot of file sharing apps in the Google Play store, this is the first we've seen that can create an ad-hoc network for sharing files between devices if no Wi-Fi network is present.

You'll need SuperBeam installed on both devices and then you'll need to pair the devices using any of a number of methods, including QR Codes, NFC, or by typing a manual code. After you've set it up, sharing is as easy as picking the files you want to share and sending them to the paired device. You can even connect Superbeam to an Android device without Superbeam installed or to a computer by connecting those computer to the ad-hoc network Superbeam creates.
